PL69895Y1 - External shielding of ventilation device - Google Patents

Description

Pattern description

The subject of the utility model is the external cover of the ventilation device, which is an element of the ventilation and air-conditioning equipment, which is installed in the ventilation openings installed in buildings from the inside of the premises for commercial or industrial purposes.

The well-known external ventilation hood, which is a component of the inVENTer and V12-Smart supply and exhaust installation by inVENTer GmbH, which is presented on the website (http://www.inventer.eu/products/inventer-ventilation-svstems/inventer-iv12-smart/) ) is designed as a housing with openings for fresh air. The cover is mounted on the outside, opposite the ventilation opening made in the building wall. The inner side of the cover is flush with the building wall and fastened to the wall with screws.

The outer cover of the ventilation device is known from the patent description KR 20150008222, which comprises a body with an outer part and an inner part, a pipe section which is installed in an air inlet made in the wall of the building and openings which are made in the inner part of the cover. The cover is mounted on the outside of the building with screws, opposite the ventilation opening made in the building wall.

An external ventilation cover is known from WO 2011096186A1 which is the closest prior art, which consists of a casing with openings providing access to fresh air. The cover is mounted on the outside of the building with screws, opposite the ventilation opening made in the building wall.

The disadvantage of these solutions is the need to install the cover from the outside of the building, often at high altitudes with the use of scaffolding or other equipment enabling work at heights, which is labor-intensive and expensive.

The outer cover of the ventilation device according to the utility model is characterized in that an elastic seal is additionally installed on the inner part for fixing the body in the air inlet of the building wall and for connection to the ventilation duct. In addition, the inner part is equipped with clamps for attaching the ventilation duct to the body. In turn, the flexible gasket has the shape of a cylindrical ring with protruding three rings and an external sealing collar. On the other hand, the inner part of the body has a partition wall.

The solution according to the utility model enables easy and safe installation of the outer cover from the side of the ventilated room.

The object of the utility model is shown in the attached drawing, in which Fig. 1 - shows the elements of the cover in a side view, Fig. 2 - shows the seal in section AA from Fig. 1, Fig. 3 - shows the first stage of assembly of the cover located outside the ventilation duct, in longitudinal section, Fig. 4 - shows the second stage of assembling the cover located in the central part of the ventilation duct, in longitudinal section, Fig. 5 - shows the III stage of the cover mounted in the ventilation duct, in longitudinal section.

The outer cover of the ventilation device (1) comprises a body (2) and an elastic seal (3). The body (2) comprises an outer part (2.1) which is situated on the external facade of the building and an internal part made in the form of a pipe section (2.2) which is mounted in the ventilation duct (6). On the outer part (2.1) of the body (2) there are ventilation openings (4) for air supply from the outside. On the pipe section (2.2) of the body (2), there are clamps (7). The flexible gasket (3) has the shape of a cylindrical ring with three protruding rings (9) and an external sealing collar (10). The main function of the outer sealing collar (10) is to adjust the cover seal to the outer wall of the building around the perimeter of the air inlet. The flexible gasket (3) is made of styrene materials, styrene copolymers or thermoplastic styrene elastomers. An elastic seal (3) is placed on the pipe section (2.2) of the body (2), the edge of the outer sealing collar (10) facing the outer part (2.1) of the body (2). Openings (11) for terminals (7) are made in the ventilation duct (6). The openings (11) of the ventilation duct (6) cooperate with the clamps (7) of the body (2) and enable tight fastening of the cover (1) and the ventilation duct (6).

A ventilation duct (6) with a cover (1) at one end is installed in the air inlet (12), which is made in the wall of the building, where the cover (1) is directly facing the outside of the building facade, the diameter of the inlet opening air (12) is slightly larger than the diameter of the ventilation duct (6). The ventilation duct (6) must be pushed through the entire width of the wall before the edge of the outer sealing collar (10) of the flexible seal (3) comes to a complete stop on the exterior facade of the building. Next, the ventilation duct (6) should be moved in the opposite direction to the room, in order to obtain a tight contact of the edges of the outer sealing collar (10) with the external facade of the building and with the edges of three rings (9) located in the ventilation duct (6), embedded in the opening the air inlet (12). To fix the ventilation pipe (6) rigidly, fill the gap between it and the air inlet opening (12) with foam.

During the installation of supply and exhaust systems in which the incoming and outgoing air is simultaneously discharged, where it is necessary to separate these streams, a partition (5) was made on the pipe section (2.2) of the body (2).

The openings (4) which are made in the outer part (2.1) of the cover (1) can be arranged horizontally or vertically or at an angle for better discharge of the exhaust air and condensate.

The outer cover of the ventilation device (1) can be made of aluminum with a polymer coating or stainless steel with a polymer coating, as well as plastic or polymer.

Claims (3)

Protective reservations 1.
